hi
suppose we have a string str=hello
now suppose there is another variable str1=$str
now another variable str2.

how u will access 'hello' using str2?

2

what value you are assinging to str2?

 
str2=$str or str2=$str1
3

you mean like this:

str="Hello"
str1=$str
str2=$str1
echo str2

Not sure if this what you are looking for.

Actually there is a variable DIALPBIN=/dialp/Release/bin

i have a shell script test.sh
#!/bin/ksh

if [ "$1" = "" ];
then ## No parameters were entered
echo "Enter the fully qualified file name:"
read mInputValue
echo "the value is " $mInputValue
else
mInputValue=$1
echo "The file name entered was "$mInputValue
fi

if i entered $DIALPBIN in the command line argument like ./test.sh $DIALPBIN
then the result is :The file name entered was /dialp/Release/bin

but if i donot give the $DIALPBIN as argument, then message appears to enter fully qualified filename
then i enter $DIALPBIN
but in that case the result is :the value is $DIALPBIN.

i want that even if the command line argument is not given , the DIALPBIN should be interpreted as /dialp/Release/bin

plz help

var=$DIALPBIN

Try this...

 #!/bin/ksh
if [ "$1" = "" ];
then ## No parameters were entered
echo "Enter the fully qualified file name:"
read mInputValue
echo "The value is `eval echo $mInputValue`"
else
mInputValue=$1
echo "The file name entered was "$mInputValue
fi
